Thanks. The same code, I did this
# install Arrow 7.0.0, download the zip in this thread, open the RStudio
project and source the script (it fails)
# install Arrow 6.0.2, download the zip in this thread, open the RStudio
project and source the script (it works)
in both cases I did (my laptop uses
{{https://packagemanager.rstudio.com/all/__linux__/focal/latest}} as default
CRAN mirror)
{code:java}
Sys.setenv("NOT_CRAN" = TRUE)
devtools::install_version("arrow", "x.y.z"){code}

> [R] Error when reading integer-type columns

> Key: ARROW-15792
> URL: https://issues.apache.org/jira/browse/ARROW-15792
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Affects Versions: 7.0.0
> Reporter: Mauricio 'Pachá' Vargas Sepúlveda
> Priority: Major
> Attachments: arrow-error.zip
>
>
> I was reading files that I created on the same laptop, same R version and
> Arrow version 7.0.0. The error I get when reading int32-type columns is
> {code:java}
> > source("~/github/un_escap/hs12-historic-series/00-create-historic-series.R")
> 2012
> Error in `handle_csv_read_error()`:
> ! NotImplemented: Function 'equal' has no kernel matching input types
> (array[int32], scalar[string])
> Run `rlang::last_error()` to see where the error occurred. {code}
> Here's a minimal example of the code that caused this
> {code:java}
> library(arrow)
> library(dplyr)
> d <- open_dataset("aggregate_level=0",
> partitioning = c("trade_flow", "year", "reporter_iso"))
> d %>%
> select(reporter, reporter_code, reporter_iso) %>%
> collect() {code}
> After going back to Arrow R package v6.0.2, it worked. Here "reporter_code"
> is numeric.
> I've attached a zip with the data.
